ST25DV-PWM series dynamic NFC tags

These NFC Forum Type 5 dynamic tags operate in the high-frequency (HF) 13.56 MHz range and comply with the NFC-V Technology specification from the NFC Forum. The data stored in these Type 5 tags is transferred natively to NFC smartphones or professional NFC/RFID HF readers that support the NFC Forum standardized NFC Data Exchange Format (NDEF).

The ST25DV-PWM IC provides a live update of PWM parameters by contactless interface, enhancing the user experience. With the ST25DV-PWM IC, the MCU is not required, and there is no need for an external oscillator, significantly reducing solution cost. Additional features such as TruST25^TM digital signature, ensuring the die authenticity, and password-protected areas offer high level of security and data integrity.

The rich developer ecosystem (evaluation boards, software tools, mobile apps, and more) available for ST25DV-PWM tags speeds up development and time to market.

ST25DV-PWM series benefits from STMicroelectronics 10-year longevity program that ensures continuous supply for 10 years.

Applications

Setting a power level, speed or rotor position is a common way to control motors in industrial and consumer applications and is easily handled using PWM (Pulse Width Modulation) signals. Combining NFC connectivity with PWM outputs in a single device delivers high added value and a cost-optimized solution for a wide range of applications including lighting, motor control, power supplies and many more.
